The report of the 20th National Congress of the Communist Party of China pointed out that the focus of economic development should be on the real economy, promoting new industrialization, and accelerating the construction of a manufacturing, quality, aerospace, transportation, network, and digital China. And emphasize the strategic goal of "building a modern industrial system that is independent, controllable, safe, reliable, and highly competitive". Solidly promoting new industrialization is an inevitable requirement for China's economic development in the new era. The foundation is becoming increasingly solid, the starting point is constantly rising, and the prospects are becoming increasingly broad. Valuable explorations have been made in transforming development methods, innovating development paths, and improving development efficiency. Made in China is making great strides towards the high-end of the world value chain. However, it must be recognized that solidly promoting new industrialization and building a modern industrial system that is independent, controllable, safe, reliable, and highly competitive is not a single task. It is necessary to have a correct understanding of the relationship between safety and development, supply and demand, innovation and enterprises, and continue to work for a long time in order to truly achieve industrial upgrading and transfer, while enhancing the continuity and competitiveness of industrial development, Continuously optimize production layout. Autonomy, controllability, safety, and reliability are the first goals for achieving new industrialization. Security is the prerequisite for development, and development is the guarantee of security. To solidly promote new industrialization, efforts must be made to achieve a dynamic balance between security and development. If the situation where core technology is subject to human constraints is not fundamentally changed, and the weak links of "bottleneck" and "chain drop" are not consolidated and fixed, new industrialization cannot be independently controlled, safe and reliable, and China's macroeconomic security has always been difficult to ensure. However, if we do not actively adapt to the new wave of scientific and technological revolution and industrial transformation, and apply high-tech to the transformation and upgrading of industrial manufacturing and the construction of modern industrial system, we will not be able to truly transform science and technology as the first productive force and the first competitiveness into the first driving force to promote social and economic development. Therefore, it is necessary to further grasp the internal connection between security and development, grasp the main contradictions and aspects, continue to promote major key core technology breakthroughs and the digital, intelligent, and green transformation of the manufacturing industry, and achieve coordinated promotion of security and development. Strengthening supply side structural reform and balancing the relationship between supply and demand is a major issue at present. Supply and demand are the two ends of the industrial chain, but also the two sides of economic development. Solidly promoting new industrialization requires both improving supply quality and meeting market demand through supply side structural reform
